For several mutations, you can either do a more complicated protocol once, or
do an easy one several times.  I have tried it both ways with Promega's
Altered Sites kit (the more complicated way), and Stratagene's QuickChange
kit (the easier way).  We made 9 simultaneous mutations with the Altered
Sites kit, the protocol is easy and straightforward, but takes several days.
I would be tempted to try Promega's Gene Editor if I were to do this again.

Good luck!
